A 4.5-year-old dog was anaesthetised to undergo a partial pancreatectomy for insulinoma removal, an insulin-secreting pancreatic tumour causing hypoglycaemia. The patient was premedicated with dexmedetomidine (2 μg/kg) and maropitant (1 mg/kg) intravenously. Anaesthesia was induced with alfaxalone (0.5 mg/kg) and diazepam (0.2 mg/kg) intravenously and maintained with a dexmedetomidine constant-rate infusion of 1 μg/kg/h and isoflurane in 70% oxygen. A bilateral transversus abdominis plane block was performed with ropivacaine (0.3% 1 ml/kg) divided into four points. Additional intraoperative analgesia included ketamine, fentanyl and methadone intravenously. Lactated Ringer's solution was administered, and glucose supplementation was adjusted based on glycaemia. Postoperatively, the patient was comfortable and required no analgesia for the 48-hour hospitalisation period, but presented mild hyperglycaemia. This case reports the successful management of an insulinoma with a dexmedetomidine constant-rate infusion and opioid-sparing multimodal analgesia.
